Definitions
- This application relates to the field of electronic device technologies, and in particular, to a display module and an electronic device.
- a flexible display has advantages of being light, thin, non-fragile, and foldable and rollable. Therefore, the flexible display is widely used in electronic products such as a mobile phone.
- a support sheet is disposed at the bottom of the conventional flexible display to support the flexible display, so that a surface collapse problem of the flexible display is resolved.
- the support sheet when the support sheet is relatively thick, the support sheet restricts the flexible display from bending, and it is difficult for the mobile phone to be folded.
- the support sheet is relatively thin, although the support sheet does not restrict the flexible display from bending, the excessively thin support sheet has insufficient structural strength, and cannot appropriately support the flexible display.
- This application provides a display module and an electronic device that have a support that is easily folded and has sufficient support strength.
- this application provides a display module.
- the display module includes a display and a support.
- the display includes a first non-bending region, a bending region, and a second non-bending region that are sequentially connected.
- the bending region is connected between the first non-bending region and the second non-bending region.
- the support is fastened to a non-display side of the display.
- the support includes a first metal plate, a second metal plate, and a third metal plate that are sequentially connected.
- the second metal plate is connected between the first metal plate and the third metal plate.
- the first metal plate is disposed facing the first non-bending region.
- the second metal plate is disposed facing the bending region.
- the third metal plate is disposed facing the second non-bending region.
- the second metal plate can be bent.
- the second metal plate is provided with at least two first elongated through hole groups.
- the at least two first elongated through hole groups are arranged in a first direction.
- Each first elongated through hole group includes a plurality of first elongated through holes.
- Each first elongated through hole extends in the first direction.
- a plurality of first elongated through holes in a same first elongated through hole group are arranged at intervals in a second direction, and the second direction is different from the first direction.
- Each first elongated through hole includes a first end part, a middle part, and a second end part that sequentially communicate. In the second direction, widths of the first end part and the second end part are both greater than a width of the middle part.
- the second metal plate is provided with the at least two first elongated through hole groups, and each first elongated through hole group includes the plurality of first elongated through holes, so that excessive stress concentration of the second metal plate is avoided, to ensure that the second metal plate has better flexibility.
- the second metal plate has less impact on bending of the display.
- the width of the middle part of the first elongated through hole is relatively narrow, there is a relatively large quantity of remaining materials between two adjacent first elongated through holes in the second direction. In this way, the second metal plate has sufficient strength.
- the widths of the first end part and the second end part are relatively wide, even if the width of the middle part is relatively narrow, a volume of the first elongated through hole is not reduced. In this way, when the second metal plate has sufficient strength, the flexibility of the second metal plate does not significantly decrease. In other words, hardness of the second metal plate in this embodiment is moderate.
- the second metal plate when the electronic device is in an open state, the second metal plate has sufficient hardness to support the bending region of the display, to prevent the bending region of the display from collapsing, that is, ensure that the display has better surface flatness. In the process of unfolding or folding the electronic device, because the second metal plate has better flexibility, the second metal plate has less impact on the bending of the display.
- a first support plate, a second support plate, and a third support plate of a rotating apparatus are generally provided with a plurality of grooves or through holes.
- the groove or the through hole may be used as a shelter for a component or configured to lock a fastener.
- a peripheral edge of the elongated through hole can squeeze an optical clear adhesive with large squeezing force, the optical clear adhesive protrudes, and the display is prone to have problems such as a black spot or a bright line.
- the second metal plate when the second metal plate has sufficient strength, the second metal plate can resist the squeezing force, on the second metal plate, of the peripheral edges of the grooves or the through holes. Therefore, the optical clear adhesive is prevented from protruding due to excessive squeezing, to avoid the display having the problems such as the black spot or the bright line.
- a length of the first end part is less than a length of the middle part.
- a length of the second end part is less than the length of the middle part.
- the length of the middle part of the first elongated through hole is relatively long, and the lengths of the first end part and the second end part are both relatively short. Therefore, the quantity of remaining materials between two adjacent first elongated through holes in the second direction further increases. In this way, the strength of the second metal plate is better. In this case, when the second metal plate has sufficient strength, the second metal plate can resist the squeezing force, on the second metal plate, of the peripheral edges of the grooves or the through holes. Therefore, the optical clear adhesive is prevented from protruding due to the excessive squeezing, to avoid the display having the problems such as the black spot or the bright line.
- the middle part is a strip-shaped hole.
- the first end part and the second end part are both circular holes. In this case, a preparation process of the first elongated through hole is simple and is easy to operate.

- the lengths of the first end part and the second end part both range from 0.15 mm to 3 mm.
- the length of the middle part ranges from 4.5 mm to 6.5 mm. It may be understood that, with the first elongated through hole in this size, the second metal plate has both better flexibility and better strength.
- a width of a spacing part that is of the second metal plate and that is located between two adjacent first elongated through holes ranges from 0.2 mm to 0.3 mm. In this way, in the second direction, there is a relatively large quantity of remaining materials between two adjacent first elongated through holes, to ensure that the second metal plate has better strength.
- a length of a spacing part that is of the second metal plate and that is located between two adjacent first elongated through holes ranges from 0.4 mm to 0.6 mm.
- the second metal plate in the first direction, there is a relatively large quantity of remaining materials between two adjacent first elongated through holes, to ensure that the second metal plate has better strength.
- the peripheral edges of the grooves or the through holes on the first support plate, the second support plate, and the third support plate of the rotating apparatus squeeze the second metal plate, the second metal plate has sufficient strength to resist the squeezing force, on the second metal plate, of the peripheral edges of the grooves or the through holes. Therefore, the optical clear adhesive is prevented from protruding due to the excessive squeezing, to avoid the display having the problems such as the black spot or the bright line.
- a plurality of first elongated through holes of two adjacent first elongated through hole groups are disposed in a cross manner.
- the second metal plate is divided into a plurality of parts by the first elongated through holes.
- the second metal plate has no continuous part.
- the flexibility of the second metal plate is further improved. In this way, in the process of unfolding or folding the electronic device, the second metal plate has better flexibility, and the second metal plate has less impact on the bending of the display.
- the second metal plate is provided with two second elongated through hole groups.
- Each second elongated through hole group includes a plurality of second elongated through holes extending in the first direction.
- a plurality of second elongated through holes in a same second elongated through hole group are arranged at intervals in the second direction.
- the second metal plate includes a first side surface and a second side surface that are disposed opposite to each other.
- One second elongated through hole group is disposed close to the first side surface, and each second elongated through hole penetrates the first side surface.
- Another second elongated through hole group is disposed close to the second side surface, and each second elongated through hole penetrates the second side surface.
- the second metal plate is provided with the two second elongated through hole groups, and each second elongated through hole group includes the plurality of second elongated through holes, so that the excessive stress concentration of the second metal plate is further avoided, to ensure that the second metal plate has better flexibility.
- the second metal plate has less impact on the bending of the display.
- each second elongated through hole of the one second elongated through hole group penetrates the first side surface of the second metal plate, and each second elongated through hole of the another second elongated through hole group penetrates the second side surface of the second metal plate, so that local stress concentration on a side part of the second metal plate is prevented.
- the second elongated through hole can absorb stress of the display module in a bending process. In other words, this avoids that the display module is difficultly bent due to excessive stress on the side part of the second metal plate.
- each second elongated through hole includes a third end part and a main part that communicate with each other.
- the main part penetrates the first side surface or the second side surface.
- a width of the third end part is greater than a width of the main part.
- the width of the main part of the second elongated through hole is relatively narrow, there is a relatively large quantity of remaining materials between the second elongated through hole and an adjacent first elongated through hole in the second direction. In this way, the strength of the second metal plate is further improved.
- the width of the third end part is relatively wide, even if the width of the main part is relatively narrow, a volume of the second elongated through hole is not reduced. In this way, when the second metal plate has sufficient strength, the flexibility of the second metal plate does not significantly decrease.
- a length of the third end part is less than a length of the main part.
- the length of the main part of the second elongated through hole is relatively long, and the length of the third end part is relatively short. Therefore, the quantity of remaining materials between two adjacent second elongated through holes in the second direction further increases. In this way, the strength of the second metal plate is better. In this way, when the second metal plate has sufficient strength, the second metal plate can resist the squeezing force, on the second metal plate, of the peripheral edges of the grooves or the through holes. Therefore, the optical clear adhesive is prevented from protruding due to the excessive squeezing, to avoid the display having the problems such as the black spot or the bright line.
- the support further includes a fourth metal plate and a fifth metal plate that face the bending region of the display.
- the first metal plate, the fourth metal plate, the fifth metal plate, the second metal plate, and the third metal plate are sequentially connected.
- the fourth metal plate is provided with at least two first elongated through hole groups.
- the fourth metal plate is provided with a plurality of first elongated through hole groups, overall hardness and rigidity of the fourth metal plate are moderate. In other words, some regions of the support have better flexibility. In this case, a quantity of regions of the support that have better flexibility may increase. Therefore, when the support is fastened to the display, the fourth metal plate may be fastened to a region with a larger bending angle in the bending region of the display, to ensure that the bending region of the display has a better bending effect. In addition, the fifth metal plate may be fastened to a region with a smaller bending angle in the bending region of the display, to ensure that the support has sufficient strength to support the display.
- a thickness of the support ranges from 0.1 mm to 0.5 mm. In this case, the thickness of the support is moderate, so that the support has better rigidity and flexibility, and the support does not greatly increase a thickness of the display module.
- the support further includes buffers.
- the buffers are disposed in the first elongated through holes, and are connected to the second metal plate.
- the buffer can absorb squeezing force, on the second metal plate, of peripheral edges of some grooves or through holes. Therefore, the optical clear adhesive is prevented from protruding due to the excessive squeezing, to avoid the display having the problems such as the black spot or the bright line.
- the support has high integrity.
- the support has sufficient strength to resist the squeezing force, on the second metal plate, of the peripheral edges of the grooves or the through holes. Therefore, the optical clear adhesive is prevented from protruding due to the excessive squeezing, to avoid the display having the problems such as the black spot or the bright line.

Chinese Patent Application No. 202020235494.2, filed with the China National Intellectual Property Administration on February 29, 2020 - This application relates to the field of electronic device technologies, and in particular, to a display module and an electronic device.
- A flexible display has advantages of being light, thin, non-fragile, and foldable and rollable. Therefore, the flexible display is widely used in electronic products such as a mobile phone. However, in a conventional mobile phone, hardness of a flexible display is poor, and a surface collapse phenomenon is prone to occur. Therefore, a support sheet is disposed at the bottom of the conventional flexible display to support the flexible display, so that a surface collapse problem of the flexible display is resolved. However, when the support sheet is relatively thick, the support sheet restricts the flexible display from bending, and it is difficult for the mobile phone to be folded. When the support sheet is relatively thin, although the support sheet does not restrict the flexible display from bending, the excessively thin support sheet has insufficient structural strength, and cannot appropriately support the flexible display.
- This application provides a display module and an electronic device that have a support that is easily folded and has sufficient support strength.
- According to a first aspect, this application provides a display module. The display module includes a display and a support. The display includes a first non-bending region, a bending region, and a second non-bending region that are sequentially connected. In other words, the bending region is connected between the first non-bending region and the second non-bending region. The support is fastened to a non-display side of the display. The support includes a first metal plate, a second metal plate, and a third metal plate that are sequentially connected. The second metal plate is connected between the first metal plate and the third metal plate. The first metal plate is disposed facing the first non-bending region. The second metal plate is disposed facing the bending region. The third metal plate is disposed facing the second non-bending region. The second metal plate can be bent.
- The second metal plate is provided with at least two first elongated through hole groups. The at least two first elongated through hole groups are arranged in a first direction. Each first elongated through hole group includes a plurality of first elongated through holes. Each first elongated through hole extends in the first direction. A plurality of first elongated through holes in a same first elongated through hole group are arranged at intervals in a second direction, and the second direction is different from the first direction.
- Each first elongated through hole includes a first end part, a middle part, and a second end part that sequentially communicate. In the second direction, widths of the first end part and the second end part are both greater than a width of the middle part.
- It may be understood that the second metal plate is provided with the at least two first elongated through hole groups, and each first elongated through hole group includes the plurality of first elongated through holes, so that excessive stress concentration of the second metal plate is avoided, to ensure that the second metal plate has better flexibility. In other words, in a process of unfolding or folding an electronic device, because the second metal plate has better flexibility, the second metal plate has less impact on bending of the display.
- In this implementation, when the first elongated through hole is disposed in an approximate dumbbell shape, on one hand, because the width of the middle part of the first elongated through hole is relatively narrow, there is a relatively large quantity of remaining materials between two adjacent first elongated through holes in the second direction. In this way, the second metal plate has sufficient strength. On another hand, because the widths of the first end part and the second end part are relatively wide, even if the width of the middle part is relatively narrow, a volume of the first elongated through hole is not reduced. In this way, when the second metal plate has sufficient strength, the flexibility of the second metal plate does not significantly decrease. In other words, hardness of the second metal plate in this embodiment is moderate. It may be understood that, when the electronic device is in an open state, the second metal plate has sufficient hardness to support the bending region of the display, to prevent the bending region of the display from collapsing, that is, ensure that the display has better surface flatness. In the process of unfolding or folding the electronic device, because the second metal plate has better flexibility, the second metal plate has less impact on the bending of the display.
- In addition, a first support plate, a second support plate, and a third support plate of a rotating apparatus are generally provided with a plurality of grooves or through holes. The groove or the through hole may be used as a shelter for a component or configured to lock a fastener. When the electronic device is in the open state, if a user presses the screen, peripheral edges of the grooves or the through holes on the first support plate, the second support plate, and the third support plate of the rotating apparatus are prone to squeeze the second metal plate. Because stress of the peripheral edges of the grooves or the through holes is concentrated, a peripheral edge of the elongated through hole can squeeze an optical clear adhesive with large squeezing force, the optical clear adhesive protrudes, and the display is prone to have problems such as a black spot or a bright line. In this case, when the second metal plate has sufficient strength, the second metal plate can resist the squeezing force, on the second metal plate, of the peripheral edges of the grooves or the through holes. Therefore, the optical clear adhesive is prevented from protruding due to excessive squeezing, to avoid the display having the problems such as the black spot or the bright line.
- In an implementation, in the first direction, a length of the first end part is less than a length of the middle part. A length of the second end part is less than the length of the middle part.
- In this implementation, the length of the middle part of the first elongated through hole is relatively long, and the lengths of the first end part and the second end part are both relatively short. Therefore, the quantity of remaining materials between two adjacent first elongated through holes in the second direction further increases. In this way, the strength of the second metal plate is better. In this case, when the second metal plate has sufficient strength, the second metal plate can resist the squeezing force, on the second metal plate, of the peripheral edges of the grooves or the through holes. Therefore, the optical clear adhesive is prevented from protruding due to the excessive squeezing, to avoid the display having the problems such as the black spot or the bright line.
- In an implementation, the middle part is a strip-shaped hole. The first end part and the second end part are both circular holes. In this case, a preparation process of the first elongated through hole is simple and is easy to operate.
- In an implementation, in the second direction, the widths of the first end part and the second end part both range from 0.15 mm to 0.3 mm. The width of the middle part ranges from 0.1 mm to 0.2 mm. In the first direction, the lengths of the first end part and the second end part both range from 0.15 mm to 3 mm. The length of the middle part ranges from 4.5 mm to 6.5 mm. It may be understood that, with the first elongated through hole in this size, the second metal plate has both better flexibility and better strength.
- In an implementation, in the second direction, a width of a spacing part that is of the second metal plate and that is located between two adjacent first elongated through holes ranges from 0.2 mm to 0.3 mm. In this way, in the second direction, there is a relatively large quantity of remaining materials between two adjacent first elongated through holes, to ensure that the second metal plate has better strength.
- In an implementation, in the first direction, a length of a spacing part that is of the second metal plate and that is located between two adjacent first elongated through holes ranges from 0.4 mm to 0.6 mm.
- It may be understood that, in the first direction, there is a relatively large quantity of remaining materials between two adjacent first elongated through holes, to ensure that the second metal plate has better strength. In this case, when the peripheral edges of the grooves or the through holes on the first support plate, the second support plate, and the third support plate of the rotating apparatus squeeze the second metal plate, the second metal plate has sufficient strength to resist the squeezing force, on the second metal plate, of the peripheral edges of the grooves or the through holes. Therefore, the optical clear adhesive is prevented from protruding due to the excessive squeezing, to avoid the display having the problems such as the black spot or the bright line.
- In an implementation, a plurality of first elongated through holes of two adjacent first elongated through hole groups are disposed in a cross manner. In this way, when sections are made in a Y-axis direction at most positions on the second metal plate, the second metal plate is divided into a plurality of parts by the first elongated through holes. In other words, the second metal plate has no continuous part. In this case, the flexibility of the second metal plate is further improved. In this way, in the process of unfolding or folding the electronic device, the second metal plate has better flexibility, and the second metal plate has less impact on the bending of the display.
- In an implementation, the second metal plate is provided with two second elongated through hole groups. Each second elongated through hole group includes a plurality of second elongated through holes extending in the first direction. A plurality of second elongated through holes in a same second elongated through hole group are arranged at intervals in the second direction. In the first direction, the second metal plate includes a first side surface and a second side surface that are disposed opposite to each other. One second elongated through hole group is disposed close to the first side surface, and each second elongated through hole penetrates the first side surface. Another second elongated through hole group is disposed close to the second side surface, and each second elongated through hole penetrates the second side surface.
- It may be understood that the second metal plate is provided with the two second elongated through hole groups, and each second elongated through hole group includes the plurality of second elongated through holes, so that the excessive stress concentration of the second metal plate is further avoided, to ensure that the second metal plate has better flexibility. In other words, in the process of unfolding or folding the electronic device, because the second metal plate has better flexibility, the second metal plate has less impact on the bending of the display.
- In addition, each second elongated through hole of the one second elongated through hole group penetrates the first side surface of the second metal plate, and each second elongated through hole of the another second elongated through hole group penetrates the second side surface of the second metal plate, so that local stress concentration on a side part of the second metal plate is prevented. In this case, in the process of unfolding or folding the electronic device, the second elongated through hole can absorb stress of the display module in a bending process. In other words, this avoids that the display module is difficultly bent due to excessive stress on the side part of the second metal plate.
- In an implementation, each second elongated through hole includes a third end part and a main part that communicate with each other. The main part penetrates the first side surface or the second side surface. In the second direction, a width of the third end part is greater than a width of the main part.
- In this implementation, when the second elongated through hole is disposed in an approximate match shape, on one hand, because the width of the main part of the second elongated through hole is relatively narrow, there is a relatively large quantity of remaining materials between the second elongated through hole and an adjacent first elongated through hole in the second direction. In this way, the strength of the second metal plate is further improved. On another hand, because the width of the third end part is relatively wide, even if the width of the main part is relatively narrow, a volume of the second elongated through hole is not reduced. In this way, when the second metal plate has sufficient strength, the flexibility of the second metal plate does not significantly decrease.
- In an implementation, in the first direction, a length of the third end part is less than a length of the main part. In this implementation, the length of the main part of the second elongated through hole is relatively long, and the length of the third end part is relatively short. Therefore, the quantity of remaining materials between two adjacent second elongated through holes in the second direction further increases. In this way, the strength of the second metal plate is better. In this way, when the second metal plate has sufficient strength, the second metal plate can resist the squeezing force, on the second metal plate, of the peripheral edges of the grooves or the through holes. Therefore, the optical clear adhesive is prevented from protruding due to the excessive squeezing, to avoid the display having the problems such as the black spot or the bright line.
- In an implementation, the support further includes a fourth metal plate and a fifth metal plate that face the bending region of the display. The first metal plate, the fourth metal plate, the fifth metal plate, the second metal plate, and the third metal plate are sequentially connected. The fourth metal plate is provided with at least two first elongated through hole groups.
- In this implementation, because the fourth metal plate is provided with a plurality of first elongated through hole groups, overall hardness and rigidity of the fourth metal plate are moderate. In other words, some regions of the support have better flexibility. In this case, a quantity of regions of the support that have better flexibility may increase. Therefore, when the support is fastened to the display, the fourth metal plate may be fastened to a region with a larger bending angle in the bending region of the display, to ensure that the bending region of the display has a better bending effect. In addition, the fifth metal plate may be fastened to a region with a smaller bending angle in the bending region of the display, to ensure that the support has sufficient strength to support the display.
- In an implementation, a thickness of the support ranges from 0.1 mm to 0.5 mm. In this case, the thickness of the support is moderate, so that the support has better rigidity and flexibility, and the support does not greatly increase a thickness of the display module.
- In an implementation, the support further includes buffers. The buffers are disposed in the first elongated through holes, and are connected to the second metal plate.
- It may be understood that, when the peripheral edges of the grooves or the through holes on the first support plate, the second support plate, and the third support plate of the rotating apparatus squeeze the second metal plate, the buffer can absorb squeezing force, on the second metal plate, of peripheral edges of some grooves or through holes. Therefore, the optical clear adhesive is prevented from protruding due to the excessive squeezing, to avoid the display having the problems such as the black spot or the bright line.
- In addition, no hollow region due to the first elongated through hole exists on the support, so that the support has high integrity. In this way, the support has sufficient strength to resist the squeezing force, on the second metal plate, of the peripheral edges of the grooves or the through holes. Therefore, the optical clear adhesive is prevented from protruding due to the excessive squeezing, to avoid the display having the problems such as the black spot or the bright line.
- According to a second aspect, this application provides an electronic device. The electronic device includes a first housing, a second housing, and the display module described above. The first non-bending region of the display of the display module is fastened to the first housing. The second non-bending region is fastened to the second housing. The first housing and the second housing can be folded relative to each other to a closed state, or unfolded relative to each other to an open state. When the first housing and the second housing are in the closed state, the bending region and the second metal plate are bent.
- In this implementation, the support has advantages of being easily folded and having sufficient support strength. When the support is used in the display module and the electronic device, the display module and the electronic device are also easily folded and have stable overall strength.

FIG. 1 is a schematic diagram of a structure of an electronic device in an open state according to an embodiment of this application. Anelectronic device 100 may be a tablet computer, a mobile phone, a camera, a personal computer, a notebook computer, a vehicle-mounted device, or a wearable device. In the embodiment shown inFIG. 1 , theelectronic device 100 is described by using the mobile phone as an example. For ease of description, as shown inFIG. 1 , a width direction of theelectronic device 100 is defined as an X axis. A length direction of theelectronic device 100 is a Y axis. A thickness direction of theelectronic device 100 is a Z axis. - With reference to
FIG. 1 ,FIG. 2 is a schematic diagram of a structure of the electronic device shown inFIG. 1 in a closed state. - The
electronic device 100 includes afirst housing 10, asecond housing 20, and adisplay module 30. Thefirst housing 10 and thesecond housing 20 can be unfolded relative to each other to be in an open state. Thefirst housing 10 and thesecond housing 20 can alternatively be folded relative to each other to be in a closed state. In other words, thefirst housing 10 and thesecond housing 20 can be switched between the closed state and the open state.FIG. 1 shows that theelectronic device 100 is in the open state.FIG. 2 shows that theelectronic device 100 is in the closed state. In this application, an example in which thefirst housing 10 and thesecond housing 20 are unfolded and folded relative to an X-axis direction is used for description. - In addition, the
display module 30 may be configured to display an image, a text, a video, and the like. Thedisplay module 30 includes afirst part 34, asecond part 35, and athird part 36 that are sequentially connected. Thesecond part 35 is connected between thefirst part 34 and thethird part 36. Thefirst part 34, thesecond part 35, and thethird part 36 are located on a same side of thefirst housing 10 and thesecond housing 20. In addition, thefirst part 34 is fastened to thefirst housing 10. Thesecond part 35 is located between thefirst housing 10 and thesecond housing 20. Thethird part 36 is fastened to thesecond housing 20. Thefirst part 34, thesecond part 35, and thethird part 36 are arranged in a Y-axis direction. Thesecond part 35 can be bent along the X axis. - It may be understood that, when the
electronic device 100 is in the open state, thefirst part 34, thesecond part 35, and thethird part 36 are approximately at 180° (where a slight deviation is allowed, for example, 165°, 177°, or 185°). In this case, thedisplay module 30 has a continuous large-area display region. In other words, thedisplay module 30 can implement large-screen display. Therefore, user experience is better. When theelectronic device 100 is in the closed state, thedisplay module 30 is folded. Specifically, thesecond part 35 is bent. Thefirst part 34 and thethird part 36 superimpose each other. In this case, an unfolded area of thedisplay module 30 is relatively small, and this helps reduce a probability of damage to thedisplay module 30. - In addition,
FIG. 2 shows that, when theelectronic device 100 is in the closed state, thedisplay module 30 is located between thefirst housing 10 and thesecond housing 20. In other words, thedisplay module 30 can be folded inward. In another implementation, when theelectronic device 100 is in the closed state, thefirst housing 10 and thesecond housing 20 may alternatively be located between thefirst part 34 and thethird part 36. In other words, thedisplay module 30 may be folded outward. - In addition,
FIG. 1 andFIG. 2 both show that theelectronic device 100 may be folded once. In another implementation, theelectronic device 100 may alternatively be folded for a plurality of times. In other words, thedisplay module 20 may include a plurality of parts. Every two parts may be folded relative to each other. - It may be understood that the
first housing 10 and thesecond housing 20 have a plurality of connection relationships, for example, a rotatable connection, a slidable connection, a rotatable and slidable connection, and a detachable fastening connection. In this embodiment, an example in which thefirst housing 10 is rotatably connected to thesecond housing 20 is used for description. Refer toFIG. 3 andFIG. 4 .FIG. 3 is a partial schematic exploded view of theelectronic device 100 shown inFIG. 1 .FIG. 4 is a schematic diagram in which a rotating apparatus of the electronic device shown inFIG. 3 is mounted on the first housing and the second housing. Theelectronic device 100 further includes arotating apparatus 40. Therotating apparatus 40 is rotatably connected to thefirst housing 10 and thesecond housing 20. Therotating apparatus 40 enables thefirst housing 10 and thesecond housing 20 to rotate relative to each other for folding or unfolding. Therotating apparatus 40 is located between thefirst housing 10 and thesecond housing 20, and therotating apparatus 40 is disposed opposite to thesecond part 35 of thedisplay module 30. - The
rotating apparatus 40 includes afirst support plate 41, asecond support plate 42, and athird support plate 43. Thesecond support plate 42 is located between thefirst support plate 41 and thethird support plate 43. In addition, thefirst support plate 41, thesecond support plate 42, and thethird support plate 43 are disposed facing thesecond part 35 of thedisplay module 30. - In addition, one side of the
second support plate 42 is movably connected to thefirst support plate 41. The other side of thesecond support plate 42 is also movably connected to thethird support plate 43. It may be understood that the movable connection may be a rotatable connection, a slidable connection, a rotatable and slidable connection, or a detachable fastening connection. In other words, thefirst support plate 41, thesecond support plate 42, and thethird support plate 43 are movable with each other. In addition, one side, away from thesecond support plate 42, of thefirst support plate 41 is rotatably connected to thefirst housing 10. One side, away from thesecond support plate 42, of thethird support plate 43 is rotatably connected to thesecond housing 20. In this case, the first supportingplate 41, the second supportingplate 42, and the third supportingplate 43 cooperate with each other, and thefirst housing 10 and thesecond housing 20 can rotate relative to each other for folding or unfolding. - It may be understood that, when the
electronic device 100 is unfolded to the open state, thefirst support plate 41, thesecond support plate 42, and thethird support plate 43 jointly support thesecond part 35 of thedisplay module 30. -
FIG. 5 is a schematic exploded view of the display module of the electronic device shown inFIG. 4 . Thedisplay module 30 includes adisplay 31 and asupport 32. Thedisplay 31 is configured to display an image, a text, a video, and the like. Thedisplay 31 is a flexible display. For example, thedisplay 31 may be an organic light-emitting diode (organic light-emitting diode, OLED) display, an active-matrix organic light-emitting diode (active-matrix organic light-emitting diode, AMOLED) display, a mini light-emitting diode (mini light-emitting diode) display, a micro light-emitting diode (micro organic light-emitting diode) display, a micro organic light-emitting diode (micro organic light-emitting diode) display, or a quantum dot light-emitting diode (quantum dot light emitting diode, QLED) display. - Refer to
FIG. 5 . With reference toFIG. 4 , thedisplay 31 includes a firstnon-bending region 3181, abending region 3182, and a secondnon-bending region 3183 that are sequentially connected. In other words, thebending region 3182 is connected between the firstnon-bending region 3181 and the secondnon-bending region 3183. The firstnon-bending region 3181 is a part of thefirst part 34 of thedisplay module 30. Thebending region 3182 is a part of thesecond part 35. The secondnon-bending region 3183 is a part of thethird part 36. Thebending region 3182 can be bent. -
FIG. 6 is a schematic diagram of the display module of the electronic device shown inFIG. 4 in a closed state. When theelectronic device 100 is in the closed state, thebending region 3182 is bent, the firstnon-bending region 3181 and the secondnon-bending region 3183 are disposed facing each other, and the firstnon-bending region 3181 partially or completely overlaps the secondnon-bending region 3183.FIG. 6 shows that thebending region 3182 is approximately water drop-shaped. In another implementation, thebending region 3182 may alternatively be semi-annular. -
FIG. 7 is a partial schematic sectional view of an implementation of the display module of the electronic device shown inFIG. 4 at a line A-A. When theelectronic device 100 is in the open state, the firstnon-bending region 3181, thebending region 3182, and the secondnon-bending region 3183 are approximately at 180° (where a slight deviation is allowed, for example, 165°, 177°, or 185°). - Refer to
FIG. 7 again. Thedisplay 31 may include arear film 311, adisplay panel 312, a polarizer (Polarizer, POL) 313, and aprotective cover 314 that are sequentially stacked. In other words, thedisplay panel 312 is located between therear film 311 and thepolarizer 313. Theprotective cover 314 is fastened to a surface, away from thedisplay panel 312, of thepolarizer 313. Therear film 311 may be configured to support thedisplay panel 312. Thedisplay panel 312 is configured to display an image, a video, and the like. Theprotective cover 314 is configured to protect thepolarizer 313, thedisplay panel 312, and the like. - In addition, the
display 31 further includes an opticalclear adhesive 315. The opticalclear adhesive 315 is fastened between thepolarizer 313 and theprotective cover 314. The opticalclear adhesive 315 not only enables display light emitted by thedisplay panel 312 to propagate outside theelectronic device 100, but also improves flexibility of thedisplay module 30. - In an implementation, the
display 31 may be a touchscreen. Thedisplay 31 can be configured to generate a touch signal based on a touch action of a user. Specifically, when the user taps an icon of camera software on thedisplay 31, thedisplay 31 can generate a touch signal based on the tapping action of the user, and transmit the touch signal to a processor (not shown in the figure) of theelectronic device 100. The processor receives the touch signal, and starts the camera software based on the touch signal. The processor may be installed in the first housing 10 (refer toFIG. 4 ), or may be installed in the second housing 20 (refer toFIG. 4 ). - The
display panel 312 may have a touch function. In other words, thedisplay panel 312 has a function of a touch panel. For example, the touch panel is embedded in a light emitting layer of thedisplay panel 312 by using an on-cell technology. In another implementation, thedisplay panel 312 may not have a touch function. In this case, thedisplay 31 further includes a touch panel (not shown in the figure). The touch panel may be fastened between theprotective cover 314 and thepolarizer 313, or may be located between thepolarizer 313 and thedisplay panel 312. - Refer to
FIG. 7 again. Thedisplay 31 includes anouter surface 316 and aninner surface 317 that are disposed opposite to each other. Theouter surface 316 of thedisplay 31 refers to a surface, facing the user, of thedisplay 31 when the user normally uses theelectronic device 100, namely, a display side of thedisplay 31. Theinner surface 317 of thedisplay 31 refers to a surface, facing the interior of theelectronic device 100, of thedisplay 31 when thedisplay module 30 is mounted on thefirst housing 10 and thesecond housing 20, namely, a non-display side of thedisplay 31. - In addition, the
support 32 is fastened to theinner surface 317 of thedisplay 31. Thesupport 32 is configured to support thedisplay 31, to improve overall strength of thedisplay module 30. In an implementation, thesupport 32 may be fastened to theinner surface 317 of thedisplay 31 by using an optical clear adhesive (OCA), a PVB adhesive, a foam adhesive, a combination thereof, or the like.FIG. 7 shows that an opticalclear adhesive 39 is disposed between thesupport 32 and theinner surface 317 of thedisplay 31. - Refer to
FIG. 7 again. In the Z-axis direction, a height HI of thesupport 32 ranges from 0.1 mm to 0.5 mm. In this case, a thickness of thesupport 32 is moderate, so that thesupport 32 has better rigidity and flexibility, and thesupport 32 does not greatly increase a thickness of thedisplay module 30. In another embodiment, the height HI of thesupport 32 may alternatively be in another numerical range. - Refer to
FIG. 5 again. Thesupport 32 includes afirst metal plate 321, asecond metal plate 322, and athird metal plate 323 that are sequentially connected. In other words, thesecond metal plate 322 is connected between thefirst metal plate 321 and thethird metal plate 323. InFIG. 5 , thefirst metal plate 321, thesecond metal plate 322, and thethird metal plate 323 are distinguished by using dashed lines. - In an implementation, the
first metal plate 321, thesecond metal plate 322, and thethird metal plate 323 form an integrated structure. In other words, thefirst metal plate 321, thesecond metal plate 322, and thethird metal plate 323 are an integral structure. In this case, connection firmness between thefirst metal plate 321, thesecond metal plate 322, and thethird metal plate 323 is better. In addition, there are relatively few steps for forming thefirst metal plate 321, thesecond metal plate 322, and thethird metal plate 323. This can reduce input costs of thesupport 42. - Specifically, the
first metal plate 321, thesecond metal plate 322, and thethird metal plate 323 that are sequentially connected are formed on an integral plate by using a CNC machining process. In another implementation, thefirst metal plate 321, thesecond metal plate 322, and thethird metal plate 323 that are sequentially connected may alternatively be formed by using an injection molding process, in a chemical corrosion manner, or another manner. - In another implementation, the
first metal plate 321, thesecond metal plate 322, and thethird metal plate 323 may alternatively be formed through welding or connected in a snap-fit fastening manner. - In an implementation, the
first metal plate 321, thesecond metal plate 322, and thethird metal plate 323 are formed in one step. It may be understood that the one-step forming includes manners such as extrusion forming, injection forming, die forming, and calendering forming. In this way, steps of a machining technology of thesupport 32 are relatively few, and cost inputs of thesupport 32 can be reduced. - Refer to
FIG. 4 andFIG. 5 . Thefirst metal plate 321 is disposed facing thefirst bending region 3181. Thefirst metal plate 321 is a part of thefirst part 34 of thedisplay module 30. Thesecond metal plate 322 is disposed facing thebending region 3182. Thesecond metal plate 322 is a part of thesecond part 35. Thethird metal plate 323 is disposed facing the secondnon-bending region 3183. Thethird metal plate 323 is a part of thethird part 36. Thesecond metal plate 322 can be bent. - Refer to
FIG. 6 again. When theelectronic device 100 is in the closed state, thesecond metal plate 322 is bent, and thefirst metal plate 321 is disposed opposite to thethird metal plate 323.FIG. 6 shows that thesupport 32 is approximately water drop-shaped. In another implementation, thesupport 32 may alternatively be annular. - Refer to
FIG. 7 again. When theelectronic device 100 is in the open state, thefirst metal plate 321, thesecond metal plate 322, and thethird metal plate 323 are approximately at 180° (where a slight deviation is allowed, for example, 165°, 177°, or 185°).FIG. 7 shows that thefirst metal plate 321, thesecond metal plate 322, and thethird metal plate 323 are at 180°. - The
first metal plate 321, thesecond metal plate 322, and thethird metal plate 323 are all made of a metal material. For example, thefirst metal plate 321, thesecond metal plate 322, and thethird metal plate 323 may be made of copper, aluminum, beryllium copper, stainless steel, a titanium alloy, or the like. In this case, thefirst metal plate 321, thesecond metal plate 322, and thethird metal plate 323 have better hardness and rigidity. -
FIG. 8 is a schematic diagram of a partial structure of the second metal plate of the display module shown inFIG. 7 . Thesecond metal plate 322 is provided with at least two first elongated through hole groups M.FIG. 8 shows three first elongated through hole groups M. In addition, a region S1 circled by using dashed lines inFIG. 8 includes a lower half of a 1st first elongated through hole group M, an entire 2nd elongated through hole group M, and an upper half of a 3rd first elongated through hole group M. A plurality of first elongated through hole groups M are arranged in the first direction.FIG. 8 shows that the first direction is the X-axis direction. Certainly, in another embodiment, the first direction may alternatively be any direction on an X-Y plane, for example, the Y-axis direction. It may be understood that the plurality of first elongated through hole groups M may be disposed parallel to the X-axis direction, but a slight deviation may be allowed, for example, 155°, 166°, or 177°. - In addition, each first elongated through hole group M includes a plurality of first elongated through
holes 3226. The plurality of first elongated throughholes 3226 are at intervals in the second direction.FIG. 8 shows that the second direction is the Y-axis direction. Certainly, in another embodiment, the second direction may alternatively be a direction on the X-Y plane. However, the second direction is different from the first direction. For example, when the first direction is the Y-axis direction, the second direction is the X-axis direction. It may be understood that in the Y-axis direction, the plurality of first elongated throughholes 3226 may be disposed parallel to a Y-axis, but a slight deviation may be allowed, for example, 155°, 166°, or 177°. In addition,FIG. 7 shows sections of the first elongated throughholes 3226 on a Y-Z plane. A shape of the first elongated throughhole 3226 on the Y-Z plane is not limited to a trapezoid shown inFIG. 7 . For example, the shape of the first elongated throughhole 3226 on the Y-Z plane may alternatively be rectangular. - In addition, each first elongated through
hole 3226 extends in the X-axis direction. It may be understood that an extension direction of the first elongated throughhole 3226 may be parallel to the X-axis direction, but a slight deviation may also be allowed, for example, 155°, 166°, or 177°. - It may be understood that the
second metal plate 322 is provided with the at least two first elongated through hole groups M, and each first elongated through hole group M includes the plurality of first elongated throughholes 3226, so that excessive stress concentration of thesecond metal plate 322 is avoided, to ensure that thesecond metal plate 322 has better flexibility. In other words, in a process of unfolding or folding theelectronic device 100, because thesecond metal plate 322 has better flexibility, thesecond metal plate 322 has less impact on bending of thedisplay 31. - Refer to
FIG. 8 again. A plurality of first elongated throughholes 3226 of two adjacent first elongated through hole groups M are arranged in a cross manner.FIG. 8 shows that an upper half of the first elongated throughhole 3226 of the 2nd first elongated through hole group M is located between two first elongated throughholes 3226 of the 1st first elongated through hole group M. In addition, a lower half of the first elongated throughhole 3226 of the 2nd first elongated through hole group M is located between two first elongated throughholes 3226 of the 3rd first elongated through hole group M. In this way, when sections are made in the Y-axis direction at most positions on thesecond metal plate 322, thesecond metal plate 322 is divided into a plurality of parts by the first elongated throughholes 3226. In other words, thesecond metal plate 322 has no continuous part. In this case, the flexibility of thesecond metal plate 322 is further improved. In this way, in the process of unfolding or folding theelectronic device 100, thesecond metal plate 322 has better flexibility, and thesecond metal plate 322 has less impact on the bending of thedisplay 31. In another embodiment, a plurality of first elongated throughholes 3226 of two adjacent first elongated through hole groups M are disposed at intervals from each other. In other words, the plurality of first elongated throughholes 3226 of two adjacent first elongated through hole groups M do not overlap each other in the X-axis direction. -
FIG. 9 is an enlarged schematic diagram of the second metal plate shown inFIG. 8 at a position B. Each first elongated throughhole 3226 includes afirst end part 1, amiddle part 2, and asecond end part 3 that sequentially communicate. In the Y-axis direction, a width of thefirst end part 1 is L1, a width of thesecond end part 3 is L2, and a width of themiddle part 2 is L3. In this case, L1 is greater than L3, and L2 is greater than L3. It may be understood that the width L1 of thefirst end part 1 and the width L2 of thesecond end part 3 may be equal or unequal. In this case, the first elongated throughhole 3226 is approximately dumbbell-shaped. - In an implementation, the
first end part 1 and thesecond end part 3 are both circular holes. Themiddle part 2 is a strip-shaped hole. In this case, a preparation process of the first elongated throughhole 3226 is simple and is easy to operate. In another implementation, thefirst end part 1 and thesecond end part 3 both may alternatively be special-shaped holes. Themiddle part 2 may alternatively be a trapezoidal hole. - It may be understood that, when the first elongated through
hole 3226 is disposed in an approximate dumbbell shape, on one hand, because the width L3 of themiddle part 2 of the first elongated throughhole 3226 is relatively narrow, there is a relatively large quantity of remaining materials between two adjacent first elongated throughholes 3226 in the Y-axis direction. In this way, thesecond metal plate 322 has sufficient strength. On another hand, because the width L1 of thefirst end part 1 and the width L2 of thesecond end part 3 are relatively wide, even if the width L3 of themiddle part 2 is relatively narrow, a volume of the first elongated throughhole 3226 is not reduced. In this way, when thesecond metal plate 322 has sufficient strength, the flexibility of thesecond metal plate 322 does not significantly decrease. In other words, hardness of thesecond metal plate 322 in this embodiment is moderate. It may be understood that, when theelectronic device 100 is in the open state, thesecond metal plate 322 has sufficient hardness to support thebending region 3182 of thedisplay 31, to prevent thebending region 3182 of thedisplay 31 from collapsing, that is, ensure that thedisplay 31 has better surface flatness. In the process of unfolding or folding theelectronic device 100, because thesecond metal plate 322 has better flexibility, thesecond metal plate 322 has less impact on the bending of thedisplay 31. - In addition, the
first support plate 41, thesecond support plate 42, and thethird support plate 43 of therotating apparatus 40 are generally provided with a plurality of grooves or through holes. The groove or the through hole may be used as a shelter for a component or configured to lock a fastener. When theelectronic device 100 is in the open state, if the user presses thescreen 30, peripheral edges of the grooves or the through holes on thefirst support plate 41, thesecond support plate 42, and thethird support plate 43 of therotating apparatus 40 are prone to squeeze thesecond metal plate 322. Because stress of the peripheral edges of the grooves or the through holes is concentrated, a peripheral edge of the elongated through hole can squeeze the opticalclear adhesive 39 with large squeezing force, the opticalclear adhesive 39 protrudes, and thedisplay 31 is prone to have problems such as a black spot or a bright line. In this case, when thesecond metal plate 322 has sufficient strength, thesecond metal plate 322 can resist the squeezing force, on thesecond metal plate 322, of the peripheral edges of the grooves or the through holes. Therefore, the opticalclear adhesive 39 is prevented from protruding due to excessive squeezing, to avoid thedisplay 31 having the problems such as the black spot or the bright line. - Refer to
FIG. 9 again. In the X-axis direction, a length of thefirst end part 1 is d1, a length of thesecond end part 3 is d2, and a length of themiddle part 2 is d3. In an implementation, d1 is less than d3, and d2 is less than d3. It may be understood that the length d1 of thefirst end part 1 and the length d2 of thesecond end part 3 may be equal or unequal. In another implementation, d1 may alternatively be greater than or equal to d3, and d2 may alternatively be greater than or equal to d3. - In this implementation, the length d3 of the
middle part 2 of the first elongated throughhole 3226 is relatively long, and the length d1 of thefirst end part 1 and the length d2 of thesecond end part 3 are both relatively short. Therefore, the quantity of remaining materials between two adjacent first elongated throughholes 3226 in the Y-axis direction further increases. In this way, the strength of thesecond metal plate 322 is better. In this way, when thesecond metal plate 322 has sufficient strength, thesecond metal plate 322 can resist the squeezing force, on thesecond metal plate 322, of the peripheral edges of the grooves or the through holes. Therefore, the opticalclear adhesive 39 is prevented from protruding due to the excessive squeezing, to avoid thedisplay 31 having the problems such as the black spot or the bright line. - In an implementation, in the X-axis direction, the length d1 of the
first end part 1 of the first elongated throughhole 3226 ranges from 0.15 mm to 3 mm. For example, d1 is equal to 0.15 mm, 0.1 mm, 2 mm, 2.29 mm, or 3 mm. The length d2 of thesecond end part 3 of the first elongated throughhole 3226 ranges from 0.15 mm to 3 mm For example, d2 is equal to 0.15 mm, 0.11 mm, 2.1 mm, 2.29 mm, or 3 mm. The length d3 of themiddle part 2 of the first elongated throughhole 3226 ranges from 4.5 mm to 6.5 mm. For example, d3 is equal to 4.55 mm, 5 mm, 5.2 mm, 6 mm, or 6.5 mm. - In addition, in the Y-axis direction, the width L1 of the
first end part 1 of the first elongated throughhole 3226 ranges from 0.15 mm to 0.3 mm. For example, L1 is equal to 0.15 mm, 0.1 mm, 0.2 mm, 0.29 mm, or 0.3 mm The width L2 of thesecond end part 3 of the first elongated throughhole 3226 ranges from 0.15 mm to 0.3 mm. For example, L2 is equal to 0.15 mm, 0.1 mm, 0.2 mm, 0.29 mm, or 0.3 mm. The width L3 of themiddle part 2 of the first elongated throughhole 3226 ranges from 0.1 mm to 0.2 mm. For example, L3 is equal to 0.15 mm, 0.1 mm, 0.11 mm, 0.19 mm, or 0.2 mm. - It may be understood that, with the first elongated through
hole 3226 in this size, thesecond metal plate 322 has both better flexibility and better strength. - Refer to
FIG. 9 again. In the Y-axis direction, a width of a spacing part that is of thesecond metal plate 322 and that is located between two adjacent first elongated throughholes 3226 isb 1. In an implementation,b 1 ranges from 0.2 mm to 0.3 mm. For example, b1 is equal to 0.2 mm, 0.22 mm, 0.26 mm, 0.29 mm, or 0.3 mm. In this way, in the Y-axis direction, there is a relatively large quantity of remaining materials between two adjacent first elongated throughholes 3226, to ensure that thesecond metal plate 322 has better strength. - Refer to
FIG. 9 again. In the X-axis direction, a length b2 of a spacing part that is of thesecond metal plate 322 and that is located between two adjacent first elongated throughholes 3226 ranges from 0.2 mm to 0.6 mm For example, b2 is equal to 0.4 mm, 0.44 mm, 0.5 mm, 0.55 mm, or 0.6 mm. In this way, in the X-axis direction, there is a relatively large quantity of remaining materials between two adjacent first elongated throughholes 3226, to ensure that thesecond metal plate 322 has better strength. In this case, when the peripheral edges of the grooves or the through holes on thefirst support plate 41, thesecond support plate 42, and thethird support plate 43 of therotating apparatus 40 squeeze thesecond metal plate 322, thesecond metal plate 322 has sufficient strength to resist the squeezing force, on thesecond metal plate 322, of the peripheral edges of the grooves or the through holes. Therefore, the opticalclear adhesive 39 is prevented from protruding due to the excessive squeezing, to avoid thedisplay 31 having the problems such as the black spot or the bright line. - Refer to
FIG. 8 again. Thesecond metal plate 322 is provided with two second elongated through hole groups N disposed at intervals. The two second elongated through hole groups N are arranged in the first direction.FIG. 8 shows that the first direction is the X-axis direction. Certainly, in another embodiment, the first direction may alternatively be a direction on the X-Y plane, for example, the Y-axis direction. In addition, a region S2 circled by using dashed lines inFIG. 8 includes the entire 1st second elongated through hole group N and an upper half of the 1st first elongated through hole group M. A region S3 circled by using dashed lines inFIG. 8 includes an entire 2nd second elongated through hole group N and the lower half of the third 1st first elongated through hole group M. - In addition, in the X-axis direction, the
second metal plate 322 includes afirst side surface 3221 and asecond side surface 3222. One second elongated through hole group N is disposed close to thefirst side surface 3221 of thesecond metal plate 322. Another second elongated through hole group N is disposed close to thesecond side surface 3222 of thesecond metal plate 322. - Each second elongated through hole group N includes a plurality of second elongated through
holes 3227. A plurality of second elongated throughholes 3227 in a same second elongated through hole group N are arranged at intervals in the second direction.FIG. 8 shows that the second direction is the Y-axis direction. Certainly, in another embodiment, the second direction may alternatively be any direction on the X-Y plane. However, the second direction is different from the first direction. For example, when the first direction is the Y-axis direction, the second direction is the X-axis direction. It may be understood that an arrangement direction of the plurality of second elongated throughholes 3227 of the same second elongated through hole group N may be parallel to the Y-axis direction, but a slight deviation may be allowed, for example, 155°, 166°, or 177°. In addition, each second elongated throughhole 3227 of the 1st second elongated through hole group N penetrates thefirst side surface 3221 of thesecond metal plate 322, and each second elongated throughhole 3227 of the 2nd second elongated through hole group N penetrates thesecond side surface 3222 of thesecond metal plate 322. - In addition, each second elongated through
hole 3227 extends in the X-axis direction. It may be understood that an extension direction of the second elongated throughhole 3227 may be parallel to the X-axis direction, but a slight deviation may also be allowed, for example, 155°, 166°, or 177°. - It may be understood that the
second metal plate 322 is provided with the two second elongated through hole groups N, and each second elongated through hole group N includes the plurality of second elongated throughholes 3227, so that the excessive stress concentration of thesecond metal plate 322 is further avoided, to ensure that thesecond metal plate 322 has better flexibility. In other words, in the process of unfolding or folding theelectronic device 100, because thesecond metal plate 322 has better flexibility, thesecond metal plate 322 has less impact on the bending of thedisplay 31. - In addition, each second elongated through
hole 3227 of the one second elongated through hole group N penetrates thefirst side surface 3221 of thesecond metal plate 322, and each second elongated throughhole 3227 of the another second elongated through hole group N penetrates thesecond side surface 3222 of thesecond metal plate 322, so that local stress concentration on a side part of thesecond metal plate 322 is prevented. In this case, in the process of unfolding or folding theelectronic device 100, the second elongated throughhole 3227 can absorb stress of thedisplay module 30 in a bending process. In other words, this avoids that thedisplay module 30 is difficultly bent due to excessive stress on the side part of thesecond metal plate 322. - In addition, the second elongated through
holes 3227 and one first elongated through hole group M are arranged crosswise to each other.FIG. 8 shows that each second elongated throughhole 3227 is located between two first elongated throughholes 3226. In other words, each second elongated throughhole 3227 overlaps the first elongated throughhole 3226. In this way, when sections are made in the Y-axis direction at any position on thesecond metal plate 322, thesecond metal plate 322 is divided into a plurality of parts by the first elongated throughholes 3226. In other words, thesecond metal plate 322 has no continuous part. In this case, the flexibility of thesecond metal plate 322 is significantly improved. - In another implementation, the second elongated through
holes 3227 and one first elongated through hole group M are arranged at intervals from each other. In other words, each second elongated throughhole 3227 and each first elongated throughhole 3226 do not overlap each other in the X-axis direction. - Refer to
FIG. 10 . Each second elongated throughhole 3227 includes athird end part 4 and amain part 5 that communicate with each other. An end part, away from thethird end part 4, of themain part 5 penetrates thefirst side surface 3221 or thesecond side surface 3222 of thesecond metal plate 322.FIG. 10 shows that themain part 5 of the second elongated throughhole 3227 of the 2nd second elongated through hole group N penetrates thesecond side surface 3222. - In the Y-axis direction, a width of the
third end part 4 is L4, and a width of themain part 5 is L5. L4 is greater than L5. In this case, the second elongated throughhole 3227 is approximately match-shaped. - In an implementation, the
third end part 4 is a circular hole, and themain part 5 is a strip-shaped hole. In this case, a preparation process of the second elongated throughhole 3227 is simple and is easy to operate. In another implementation, all thethird end parts 4 may be special-shaped holes, and themain part 5 may alternatively be a trapezoidal hole. - In this implementation, when the second elongated through
hole 3227 is disposed in an approximate match shape, on one hand, because the width L5 of themain part 5 of the second elongated throughhole 3227 is relatively narrow, there is a relatively large quantity of remaining materials between the second elongated throughhole 3227 and an adjacent first elongated throughhole 3226 in the Y-axis direction. In this way, the strength of thesecond metal plate 322 is further improved. On another hand, because the width L4 of thethird end part 4 is relatively wide, even if the width L5 of themain part 5 is relatively narrow, a volume of the second elongated throughhole 3227 is not reduced. In this way, when thesecond metal plate 322 has sufficient strength, the flexibility of thesecond metal plate 322 does not significantly decrease. - Refer to
FIG. 10 again. In the X-axis direction, a length of thethird end part 4 is d4, and a length of themain part 5 is d5. In an implementation, d4 is less than d5. In another implementation, d4 may alternatively be greater than or equal to d5. - In this implementation, the length d4 of the
main part 5 of the second elongated throughhole 3227 is relatively long, and the length d4 of thethird end part 4 is relatively short. Therefore, the quantity of remaining materials between two adjacent second elongated throughholes 3227 in the Y-axis direction further increases. In this way, the strength of thesecond metal plate 322 is better. In this way, when thesecond metal plate 322 has sufficient strength, thesecond metal plate 322 can resist the squeezing force, on thesecond metal plate 322, of the peripheral edges of the grooves or the through holes. Therefore, the opticalclear adhesive 39 is prevented from protruding due to the excessive squeezing, to avoid thedisplay 31 having the problems such as the black spot or the bright line. - In an implementation, in the X-axis direction, the length d4 of the
third end part 4 ranges from 0.15 mm to 3 mm, and the length d5 of themain part 5 ranges from 4.5 mm to 6.5 mm. In the Y-axis direction, the width L4 of thethird end part 4 ranges from 0.15 mm to 0.3 mm, and the width L5 of themain part 5 ranges from 0.1 mm to 0.2 mm. It may be understood that, with the second elongated throughhole 3227 in this size, thesecond metal plate 322 has both better flexibility and better strength. - Refer to
FIG. 10 again. In the Y-axis direction, a width of a spacing part that is of thesecond metal plate 322 and that is located between the second elongated throughhole 3227 and the adjacent first elongated throughhole 3226 is b3. In an implementation, b3 ranges from 0.2 mm to 0.3 mm. For example, b3 is equal to 0.2 mm, 0.22 mm, 0.26 mm, 0.29 mm, or 0.3 mm. In this way, in the Y-axis direction, there is a relatively large quantity of remaining materials between the second elongated throughhole 3227 and the adjacent first elongated throughhole 3226, to ensure that thesecond metal plate 322 has better strength. - Refer to
FIG. 10 again. In the X-axis direction, a length of a spacing part that is of thesecond metal plate 322 and that is located between the second elongated throughhole 3227 and the first elongated throughhole 3226 is b4. In an implementation, b4 ranges from 0.4 mm to 0.6 mm. For example, b4 is equal to 0.4 mm, 0.44 mm, 0.5 mm, 0.55 mm, or 0.6 mm. In this way, in the X-axis direction, there is a relatively large quantity of remaining materials between the second elongated throughhole 3227 and the first elongated throughhole 3226, to ensure that thesecond metal plate 322 has better strength. -
FIG. 11 is a partial schematic sectional view of another implementation of the display module of the electronic device shown inFIG. 4 at the line A-A. Thesupport 32 further includesbuffers 324, and thebuffers 324 are disposed in the first elongated throughholes 3226 and connected to thesecond metal plate 322. Thebuffer 324 may be made from a polymer material, for example, thermoplastic polyurethane (Thermoplastic polyurethane, TPU) rubber, a thermoplastic elastomer (Thermoplastic Elastomer, TPE), or rubber. Thebuffer 324 has better flexibility. Thebuffer 324 may fill a part of the first elongated throughhole 3226, or may fill the entire first elongated throughhole 3226. In this way, in the process of unfolding or folding theelectronic device 100, thesecond metal plate 322 has less impact on the bending of thedisplay 31. In another embodiment, thebuffer 324 may also be disposed in each second elongated throughhole 3227. - It may be understood that, when the peripheral edges of the grooves or the through holes on the
first support plate 41, thesecond support plate 42, and thethird support plate 43 of therotating apparatus 40 squeeze thesecond metal plate 322, thebuffer 324 can absorb squeezing force, on thesecond metal plate 322, of peripheral edges of some grooves or through holes. Therefore, the opticalclear adhesive 39 is prevented from protruding due to the excessive squeezing, to avoid thedisplay 31 having the problems such as the black spot or the bright line. - In addition, no hollow region due to the first elongated through
hole 3226 exists on thesupport 324, so that thesupport 324 has high integrity. In this way, thesupport 324 has sufficient strength to resist the squeezing force, on thesecond metal plate 322, of the peripheral edges of the grooves or the through holes. Therefore, the opticalclear adhesive 39 is prevented from protruding due to the excessive squeezing, to avoid thedisplay 31 having the problems such as the black spot or the bright line. -
FIG. 12 is a partial schematic sectional view of another implementation of the display module of the electronic device shown inFIG. 4 at the line A-A. Thesupport 32 further includes afourth metal plate 3252 and afifth metal plate 3251 that face thebending region 3182 of thedisplay 31. Thefirst metal plate 321, thefourth metal plate 3252, thefifth metal plate 3251, thesecond metal plate 322, and thethird metal plate 323 are sequentially connected. - The
fourth metal plate 3252 is provided with a plurality of first elongated through hole groups M. It may be understood that, for a manner of disposing the first elongated through hole group M in this implementation, refer to a manner of disposing the first elongated through hole group M in the foregoing implementations. Details are not described herein again. In addition, two second elongated through hole groups N may also be disposed in this implementation. For details, refer to a manner of disposing the second elongated through hole group N in the foregoing implementations. Details are not described herein again. In addition, for a manner of disposing thefifth metal plate 3251, refer to a manner of disposing thefirst metal plate 321 in the foregoing implementations. Details are not described herein again. - In this implementation, because the
fourth metal plate 3252 is provided with the plurality of first elongated through hole groups M, overall hardness and rigidity of thefourth metal plate 3252 are moderate. In other words, some regions of thesupport 32 have better flexibility. In this case, a quantity of regions of thesupport 32 that have better flexibility may increase. Therefore, when thesupport 32 is fastened to thedisplay 31, thefourth metal plate 3252 may also be fastened to a region with a larger bending angle in thebending region 3182 of thedisplay 31, to ensure that the bending region of thedisplay 31 has a better bending effect. In addition, thefifth metal plate 3251 may be fastened to a region with a smaller bending angle in thebending region 3182 of thedisplay 31, to ensure that thesupport 32 has sufficient strength to support thedisplay 31. - In another implementation, the
support 32 may further include a sixth metal plate, a seventh metal plate, ..., and an Sth metal plate. S is an integer greater than or equal to 7. At least one metal plate is provided with a first elongated through hole group M. At least one metal plate is not provided with the first elongated through hole group M. - The foregoing descriptions are merely specific implementations of this application, but are not intended to limit the protection scope of this application. Any variation or replacement readily figured out by a person skilled in the art within the technical scope disclosed in this application shall fall within the protection scope of this application. Therefore, the protection scope of this application shall be subject to the protection scope of the claims.
